Common risks, symptoms and effects of diabetes include:
Hyperglycemia (high BG): Extreme thirst, frequent urination,
dry skin, hunger, blurred vision, nausea, drowsiness, slow-healing wounds, vomiting.
Hypoglycemia (low BG): Trembling, fast heartbeat, sweating, dizziness, anxiousness, paleness, hunger, weakness/fatigue, headache, fainting.
When in doubt, diabetics must immediately check their blood sugar using a BG monitoring device, and either eat or drink something with sugar when their BG is low, or else take the appropriate medicine to counteract high blood glucose.
Symptoms and precautions are difficult, if not impossible, to identify and manage under water, and because of the scope of these potential problems, diabetics are at greater risk when it comes to diving safely.
Some medical experts disapprove of diabetics diving even today, yet in recent years many divers with the condition have proved the medical industry wrong, and shown that it is possible to pursue their passion for diving without jeopardising or sacrificing health and safety.
It’s a matter of taking the right precautions, and knowing your limits. Always speak to professionals to get an objective opinion of the state of your health before attempting to dive.
No matter how well-controlled your condition may be, if you have diabetes you can’t dive without restrictions.
The same applies to people without diabetes, of course, yet diabetics must accept that, however good their diving skills, their risks are higher.
